Maths Spl

You have to opt for National Institute of open schooling (NIOS). Here you can do the class 12th with Maths and Science as per your needs. However you can not change your stream during the current academic session.

Since you have statistics of all three years, you can apply for M.Sc. Statistics. Aggregate marks are 50% overall and 60% in statistics in your graduation.

I think you should go with B.Sc. Statistics, because B.Sc. Data Science students have big competition with B.Tech CSE students and most of the companies prefers to select the B.Tech CSE students in place of B.Sc. Students.

For doing BBA after class 12th, maths is not compulsory. Eligibility says 10+2 in any discipline. There are many colleges that offer BBA like SP Jain in the western part of India and if you are looking for Delhi NCR then colleges of DU, IP and IILM University Gurugram are the options that are available.

In most of the Flying Academies, the Physics and Maths are the mandatory requirements at class 12th level for CPL. However, other courses like Student pilot and PPL can be done on the basis of class 10th.
